Description

Technical Field

[0001] The invention relates to the technical field of welding processing, and in particular to anti-deviation welding equipment for joints in the production of hydraulic props. Background Art

[0002] ‌Hydraulic prop‌ is an important mining support equipment. It uses liquid pressure to generate working resistance and realize lifting and unloading. It is mainly divided into external injection single hydraulic prop and internal injection single hydraulic prop. The hydraulic prop is designed to provide high reliability, light weight, and is suitable for different working conditions and coal seam inclinations. The core of welding processing technology is to achieve joining by heating, high temperature or high pressure to melt or plasticize metal or other thermoplastic materials. During the welding process, the welding heat source (such as electric arc, flame, laser, etc.) heats the metal to be welded to a molten state and then connects them together. The quality of the weld will directly affect the strength and sealing of the welded joint. Therefore, the accuracy of the weld joint needs to be strictly controlled during the welding process.

[0003] When performing mobile welding on hydraulic supports, welding equipment may be affected by external forces and cause displacement and dislocation, resulting in inaccurate welding and poor welding quality.
